Application 4filed February 7', 1912. Serial No. 676,145.

Be it known that ll, JonN MUIAMMANY, a citizen olil the United States, and a i sident ot tfltanrtord, in the county oit Fan.'- tield and State otl Connecticut, have invented certain new and use'tul Improvements in lllachines tor fleritforating Master-Sheets :tor (,)perating l"vpe-ll/rriters, &e., ot which the t'ollowing is a specitieation.

lhis invention has :t'or its object to pro vidi a simple compact and easily operated machine tor` producing a perforated master-sheet adapted. to be used as a part oit the automatic typewriter operating mechanismv set :torth in another application i'or Letters .Patent of the United States .filed by me concurrently herewith, Serial No. atenei.,

The invention consists .in the improvements which I will now proceed to describe and claim.

The same re'terence characters the same parts ,in all the figures.

The supporting trame or housing` lZ is or may be ot the saine general 'torni otv the iti-ame ot 'various well known standard type w ri ters.

i represents a supply spool or roll trom which the paper sheet itil passes to the perlorating pimches and dies, said spool being journaled in l'iearings on the upper portion et the 'traine and adapted to rotate loosely and permit the unwiuding oit' the sheet.

15 represents a. Vtixcd horizontal bar constiindicate tuting the punch bed or die, said bar being provided with a row oit orifices lt correspondiug in nulnbcr to the keys ot an ordinary typewriter, each oritice constitutingl a dic adapted to cooperate with a pertmab ingl punch.

1T represents a lixed horizontal bar soparated trom the bar l5 by a narrow slot or crevice, through which the sheet. lst passes, and provided with a row of guide orifices correspomlingl in number to the punch dies .lt and registering tluzrewith. The punches lt) are adapted vto reciprocate .in the guide orifices te and in corresponding guide orifices in a flange E2() attached to the bar 17, each punch being t'ormed to cooperate with the corresponding die in cutting a circular hole in the sheet llt. The punches are reciproeated in their guides by a series oit key levers correslnnnling in number to the punches. The levers are ot angular it'orni and are 'tulerumed at 22. .lhe vert-ical arm ot each lever is engaged with shoulders Q3 on the corresponding punch lll in such manner that oscillatoryY movements ot the lever impart. rectilinear movements to the punch. 'I`he horizontal arm o't' each lever .is extended upwardly at, its outer end and provided with a linger key ist the arrangement of the levers and keys resembling that oit' the levers and keys ot well knowin typewriters, as indicated b v liigs. t and L). The levers are i'iormally supported by springs so that the punches 1E) are normally retracted, as shown by llig. o, the keys Llf being raised.

tlt'i representsI a l'eed roll located below the punches and adapted to teed the sheet tl st,epb vstep, the sheet passing partly around the t'eed roll to a receiving roll or spool 2T which is rotated, as hereinafter described, to take up the sheet as tast as it is pertorated. 'lhe `leed roll titi is journaled in bearings in the trame and to one of its ends is attached a ratchet 2S. 2f) represents an arm adapted to oscillate on the :teed roll 2li, said arm carrying a pawl 3() which is hcld by a spring 231 in engagen'lent with the ratchet 2S. ,lhe arm 2f) is oseillated con* ljointly by the spring Ill and by a reciprocating vertical rod 32 which is movable in fixed guides 33. The upper end o'tE said rod S32 is in contact lwith the arm 29 which pressed against the rod by the spring 31. With the lower end ol the rod 32 is engaged an arm 3ft 't'orining a part ot an ('iscillatory trame which in this embodiment o't the in vention is composed of longitudinal members 35, 36, a transverse rock shaft 37 rigidly connected with said members and mounted to rock on pivots 38, the outer ends of the arms 35, 3G being extended upwar lly and connected by a transverse push piece 3S). rl`he said oscillatory frame is adapted to be oscillated on the pivots 38 and thus oscillate the arm 34 which is an extension of the member 36, as shown by Fig. 3.

The outer end of the arm 34 enters a notch or recess 1-O in the rod so that the oscillating movements of said arm impart rectilinear reciprocating` movements to the rod 327 the latter being caused to alternately move the arm 29 against the stress of the spring 31 and to permit the spring to move the arm in the opposite direction. The pawl 30 is thus moved sufiiciently to impart a step-by-step rotation to the feed roll through the ratchet 28. The side members 35, 36 of the oscillatory frame are provided with upwardly projecting ears ell, to which is attached a cross bar 42. The forward arms of the key levers 2l rest on this cross bar so that whenever a key lever is depressed to project the corresponding punch 1S), the outer portion of the oscillatory frame is depressed and the arm 3d thereof is raised, thus moving the rod 32 upwardly. The arm 34C and rod 32 are normally pressed downwardly by means of springs 13.

The punches 19 are normally retracted so that when a key lever 21 is depressed it causes a partial rotation of the feed roll through the mechanism above described' before the punch reaches the sheet 1e, the punch entering and perforating the sheet just at the close of the feeding movement caused by the partial rotation of the feed roll. The oscillatory frame may be operated to cause the feeding of the sheet independently of the key levers by downward pressure on the push bar 39. rlhe receiving roll 27 is mounted loosely on a shaft l5 journaled in bearings in the supporting frame. lhe ends or heads 27 of the spool 27 are frictionally engaged to prevent loose rotation of the spool 27.

au, 46 represent a series of tension springs mounted. on the shaft i-5 and bearing against one of said heads, said springs retarding rotation of the spool 27 and at the same time pressing the other head 27L against one end of the sleeve 47 attached to the shaft 45.

48 represents a gear attached to the shaft 45 and connected through an intermediate gear 19 with a gear 50 attached to the feed roll, said gears imparting rotary movement from the feed roll to the shaft t5 in the direction indicated by the arrow in Fig. 2. Backward rotation of the shaft t5 is prevented by a gravity pawl 51, Fig. G, pivoted to the supporting frame and a ratchet 52 attached to the shaft 45 and engaged by said pawl.

rlhe central part of the feed roll 26 is provided with radial pins 5? which are adapted to enter previously formed orifices in the sheet 11i and thus cause a positive feeding movement of the' sheet. rAlhe radial pins o3 so engage the orifices 'in the sheet as to positively advance the latter and render it certain that the apertures formed by the punches 19 will be accurately spaced l' itudinally of the sheet. 1t is of course yntial that the proper engagement of the sheet and its previously formed orifices with the feed roll and ifs pins or projections 53 shall be preserved. Since the receiving roll is inormted loosely on the shaft 45, but is fricfionally engaged and driven by the springs f6 mounted on said shaft, said shaft being driven by the gear train described, the receiving roll is thereby operated to keep the sheet under the necessary tension mentioned.

1t will be seen that when the parts are in their normal positions7 as shown by lfig. 5, the pawl-carrying arm 29 is inclined at a considerable angle over the rod 32 and that the upward movement of said rod moves the arm 2f) to approximately a vertical position. The rotation of the feed roll occurs during the first part of the upward movement of the rod 32, caused by the depression of a key lever 21, and before the punch 19 carried by the depressed lever 21, reaches the she-et. When the punch encounters the sheet, the feed movement of the roll has ceased, the arm 29 having then been moved to a substantially vertical position so that its edge, in Contact with the rod is substantially parallel with the path of the rod. After this, the movement of the key lever 21 is continued sufficiently to force the punch through the sheet while the latter is at rest. @n the release of the depressed key lever the spring returns Vthe lever to its normal position. and retracts the punch. Each depression of a key 2e therefore feeds the sheet one space and causes the corresponding punch to perforate the sheet, the hole beingl spaced lengthwise of the sheet from the jvn'cceding hole, and occupying a position crosswise of the sheet corresponding to the letter or other character represented by Y the mattei' l'or which Vthe master-sheet was perforated. The key levers 21 are movable between guides 55, G, 57 which prevent their sidewise displacement.
